CEMENT-MORTAR OR CONCRETE ROOFING-TILE.

' a Specification of Letters Patent.

Application filed March 15, 1912. Serial No. 684,061.

To all whom it may concern:

Be it known that I, IGNATZ H. FREUND, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Cement-Mortar or Concrete Rooting-'Iile, of which the following is a specification. I

The use of cement-mortar or. concrete roofingtile as hitherto rovided is objectionable, under some conditions, in that they are of such construction as to cause condensation of moisture on their under surfaces when forming a roof of a room in which the air is humid; and furthermore, by reason of their solidity, do not properly insulate the atmosphere from the air in the room.

My object is to provide a cement-mortar or concrete roofing-tile of such construction as will obviate, as nearly possible, con densation of moisture thereon from the air in the room of which they i'ormithe roof,

and shall possess insulating properties,

against heat and cold, to a high degree;.andto this end I form thetile with one. or more closed chambers. therein, thereby-forming dead-air spaces disposed between the upper and lower portions of -the tile, which serve to overcome the objections above noted Referring to the accompanying drawings in which my invention 18 shown as embod ed in one of'a nuinberof forrri's 'of tile in which. it may be utilized, Figure 1 s a'plan view of a section of a roof-constructed et -tile embodying my invention, certain of the tileunits being shown in plan St !(tti0l], tll( seci 'rn on which the lowermost one of the sectioncd tile is taken being reprcsented' at a" in Fig. 6, and the-section on which the othersectioned .tile is taken beingrepresented .at'

7 Fig. 2' is a section taken at theline 2 on Fig. 1 and viewed in the direction of tlie arrow. Fig. 3 is an end view of one ofthe similar tiles. Fig. 4 is' a broken section taken at the line 4 on Fig. 3am] viewed in the direction of the arrow; and Figs. 5 and 6, sections taken at the lines and respectively on Fig. 1 and viewed in the dircc tions of the arrows. Y r r v The tile illustrated in the drawings, in so far as their external formatitr n and manner of assembiin to form a roof is concerned, are substantially the same as those commonly provided, each tile being relatively long, wide and thin and presenting! along its marginal edges on its upper surface lon gitudinally extending flanges 7, which, when the tile are ositioned in staggered, over lapping relation as represented in the drawings, on the purlins, represented at 8 and spaced apart as is usual in constructions of this character and forming a part of the skeleton roofed-structure 9, are inclosed by channeled bars 10 of concrete to cover the abutting joints betweenadjacent tile, the lower ends of the tile on their under surfaces containing concaved recessed portions 11 which extend longitudinally of the tile and which, when the'tile are positionedas illustrated, are superposed on and cover,'

the adjacent ends of the channeled bars 10, as represented in Figs. 1 and 2, thus permitting the tile to lie flatwise at their overlappiii {ends against the adjacent tile.

The illustrated, instead of bcinp solid as hithefto provided, contain closed chambers represented at 12, each file preferably containing a single chamber, though if desired a plurality of closed chambers of any suitable number may be provided therein, the chambers in the tile illustrated extendingzclosely adjacent to the! marginal edges of the tile, whereby chambers of relatively great area", as compared with the area of the tilc','. are provided therein.

The "chambers 12 in the tile may be formed from cement-mortar or concrete in any desirable manner, but referably in the operation of molding the tile in accordance with the", methods well-known to those .ltillcd'iii the molding alt, Wl'lOtlwfiQit be by having t-hecorcs,' for formin the chambers,

extend partway into" the'mo ds for molding the tile with chambers "each-closed, in the molding .operation, at oneend only and thereafter plugged at its opposite end with the same-material as thatfrom which the tile is molded, or any "other suitable mate- 1 rial, torender the chambers closed; or by..100

havi'ngthe cores extend entirely across the mold and thereafter-plugging up the endsof the openings produced thereby in the tile, to render the chambers. closed; or by inoldinginto the tile aptube or tubes, of any suitable material, which reach short of the mold and form a part of the tile when completed; or b" forming them in any other suitable manner to produce the desired closed chambers.

\Vhere the tile are formed with chambers of relatively great area as compared with the area of the tile, it is desirable that reinforcing means therefor be provided. Desirable means for this purpose areillus trated in the drawings, wherein 13 represents a reinforcing wire-mesh embedded in the bottom sections of the tile.

It will be observed that each tile containing a closed chamber, or chambers, as the case may be, constitutes a separate unitpresenting a dead-air space or spaces which are independent of. the airspaces in adjacent tile ahd are out of communication there- 'with and thus do not depend for their closure, to prevent circulation of air therethrough, upon the cementing of any joints between the open ends of adjacent tile, thereby avoiding danger of circulation of air through the air chambers in the tile.

While I have shown my invention as embodied in a roofing-tile of a particular type, I do not wish to be understood as in nding to limit it to such embodiment or to its embodiment in tile which when assembled to form a roof occupy the staggered overlapping position illustrated, as it may be embodied in any other type of cement-mortar or concrete roofing-tile and in tile designed to be assembled in end abutting relation or other desirable relation and wherein it is desirable that a closed chamber or chanr bers, forming a deadq ir space or space-i, be provided in each tile unit.

It will be manifest that by constructing tile in accordance with my invention a roof may be formed of tile units which are relatively lon r and wide and thin, and still pre sent insu ating bodies of dead-air of area suflicient to prevent, or at least greatly minimize, condensation of moisture on the under side of the roof, and in addition thereto effectually insulate the air on one side of the roof from the air on the opposite side of the roof.

i l l l i i i 2. A plurality of llOlln, rooting tiles adapted to be laid in overlapping and interlocking series, each tile being formed with longitudinally extcndinz. 'zizarginal flanges a closed on its upper surface and nmaii'iing chamber affording a deadhir recess on the under side of 1h" and end walls of which inter-sci"! 4 chamber and lying in the Filllh plane therewith, and channc .bors adapted to cover abutting flanged elgts of flanking tiles, the end of'each channel mom ber fitting in one of said reces' :1. whereby each tile of the series caus d to lie in flat wise relation omithe end of an! adj ac. tile.

A plurality of hollow reinforced roofi 75 tiles adapted to be laid in overlapping interlocking series, each tile being forum with longitudinally extending margi l flanges on its upper sazrtace and coi'itnii'liiig a closed (,lhlllljul affording a dead-air spa e J-o I a -1.'

and a re ess on the under side of the tire iiil' side and end walls of which intersect said vl nfil clmn'ibcr and lying in the same 1- tie-'itudinal plane tlicrcuitl and channel Illtllllfll'r; adapted to cover al liilllg flanged I5 edges f flanking Hits, the end of each chanhri nr-nrbcr fitting in one oi said'ijecesses, *rcbfi each tile of the iriies is'ca'uscd to lie in fiatwisc r lation oi er the end of an adjacent tile.
